Ninja Sex Party (often abbreviated as NSP) is an American musical comedy rock duo consisting of singer Dan Avidan and keyboardist Brian Wecht. They formed in 2009 in New York City and are currently based in Los Angeles. They are also part of the musical trio Starbomb with friend and collaborator Arin Hanson.
The work of Ninja Sex Party typically consists of rock or synth-pop-oriented humorous songs, frequently on the topics of sex, seduction, love or fantasy, with Avidan and Wecht respectively portraying the characters of Danny Sexbang, an idiotic, exuberant, hypersexual Jewish man who tries to hit on women with varying degrees of success; and Ninja Brian, a non-verbal, extremely homicidal ninja with whom Danny is best friends.
